already (it is unecessary to set them when they are already set to the
defaults): testconnect, sign, keep, bandwidthlimit
I also unset because they were not set to the defaults: $tmpdir =
"/var/tmp/duplicity", $nicelevel = 19. The defaults for these are:
$tmpdir = "/tmp", and $nicelevel = 0. The example configuration files
included in backupninja are confusing about these, so I've just
clarified those in the upstream source.
Then there were a couple options that were set to values that I think
should not be set: $password = "a_very_complicated_passphrase" -- I
dont think this should be set by default at all, because people will
accidentally use this passphrase by default (yuck). People should be
forced to set this. I also reset the $destdir = "/backups" setting to
be false. This value must be set, but I dont think it should be set by
default.
